I am doing a duplexer Sinclair Q2330E measurement.
I short-circuit the measuring cables and push the “Store Thru” button.

I’m connecting a duplexer.

Why is the measurement over 0dB? Marker 3 shows gain ??
What am I doing wrong ?

It looks like some strong VSWR effects. I would throw a 6 or 10 dB attenuator on the SA and TG and repeat the test. If this does not solve the problem, I would try different cables.
